The 86-year-old New Jersey Democrat is offering seats in a private suite for $2,500 a person for political action committees and $2,400 for individuals, according to The Washington Post.

An aide says the fundraiser was Lautenberg's idea. The senator and his wife celebrated his 86th birthday in January at a Gaga show at Radio City Music Hall.

Little Monsters Go Gaga for Their Lady

Lautenberg was hospitalized Feb. 15 after falling at his home and was treated for a bleeding ulcer. B-cell lymphoma was found in his stomach four days later.

Lautenberg announced in June he was cancer-free after six rounds of chemotherapy.

Lady Gaga's Outrageous Style

We don't think Lautenberg made Gaga's epic "Today" show concert last month, though, when nearly 20,000 little monsters packed the plaza in the pouring rain for an event Gaga later tweeted to be a "misfit's performance of a lifetime."
